Polling Firm Tendencies

Here are the rankings - to be constantly added to and updated - of the various polling firms in terms of their tendencies to favour one party over another. This does not necessarily equate to a deliberate bias, but instead is more reflective of the polling methods used.

As you can see, the list is not complete yet.

The following lists show each pollster's average variation from other polling firms. The numbers are the amount of percentage points a particular pollster favours or disfavours that particular party compared to other pollsters.
